How optical mouse to work?
What's principle of the physics?

Yay.Modern surface-independent optical mice work by using an optical sensor to take successive pictures of the surface the mouse is operating on. Most of these mice use LEDs to illuminate the surface that is being tracked; LED optical mice are often mislabeled as 'Laser Mice', probably due to the red LED which is used in almost all optical mice, though lasers are becoming more common, as they allow greater precision in movement detection. Changes between one frame and the next are processed by the image processing part of the chip and translated into movement on the two axes. For example, the Agilent Technologies ADNS-2610 optical mouse sensor processes 1512 frames per second: each frame is a rectangular array of 18*18 pixels, and each pixel can sense 64 different levels of gray.
Demand for advances in optical mouse technology comes in large part from competitive FPS gamers, who prefer more accurate mice for more accurate aiming. Razer USA Ltd was the first to launch the 1600 dpi Razer Diamondback which was developed together with Agilent Technologies. Razer USA Ltd was led the mouse arms race for a year before Logitech caught up with its MX518 gaming mouse which also featured a 1600 dpi optical sensor.

I wish learn it!
Shailen Sobhe said:I wonder how the mouse is able to detect motion on a perfectly uniform surface.
What if the mouse is moved at a very slow speed such that each image taken by the mouse is completely similar to each other?
An optical mouse is a computer peripheral used to control the movement of a cursor on a computer screen. It uses a light-emitting diode (LED) or laser to illuminate the surface beneath the mouse and a small camera to capture images of the surface. These images are then processed by the mouse's internal microprocessor to determine the direction and speed of movement.
A traditional mechanical mouse uses a rubber ball and internal sensors to track movement, whereas an optical mouse uses light and a camera. This makes optical mice more accurate and less prone to mechanical failures, as there are no moving parts that can wear out or collect dirt and dust.
Optical mice offer a smoother and more precise tracking experience compared to mechanical mice. They also do not require a mouse pad and can work on a variety of surfaces, including glossy or uneven ones. Additionally, they are generally more durable and have a longer lifespan.
No, there are different types of optical mice such as LED and laser mice. LED mice use a low-cost LED light source, while laser mice use a more precise laser light source. Additionally, there are also different levels of sensitivity and features, such as adjustable DPI (dots per inch) and programmable buttons, available in optical mice.
While optical mice are generally more accurate and reliable than mechanical mice, they do have some limitations. They may not work well on reflective or transparent surfaces, and they may also have difficulty tracking very fast or very slow movements. However, these limitations can be mitigated by using a quality mouse pad and adjusting the mouse's sensitivity settings.
